/**
 * SpringSession核心原理
 *  1)、@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1、给容器中添加了一个组件
 *          SessionRepository ==》 【RedisOperationsSessionRepository】: redis操作session. session的增删改查封装类
 *      2、SessionRepositoryFilter ==》 Filter： session存储过滤器，每个请求过来都必须经过filter
 *          1、创建的时候，就自动从容器中获取了SessionRepository
 *          2、原始的request,response都被包装       SessionRepositoryRequestWrapper  SessionRepositoryResponseWrapper
 *          3、以后获取session. request.getSession();
 *          //SessionRepositoryFilter
 *          4、wrappedRequest.getSession(); ==> SessionRepository 中获取到的。
 *   装饰者模式
